Science Fair Project Idea

Scientific Method

Tilt-A-Whirls, Merry-Go-Rounds, Spinning Tea Cups...does just the thought of them make you dizzy? Why should something so fun make our heads spin so long even after the ride has stopped? Learn about spins, turns, and the mixed signals that fire in our brains when the sensation of dizziness takes over. Weak stomachs, beware. This project has tests that will make your head spin!

Measuring Concussion Risk in Football and Other Contact Sports

Science Fair Project Idea

Scientific Method

Playing sports can be a lot of fun, but some sports pose higher risks of concussions, or brain injuries resulting from collisions, especially in contact sports like football. Some coaches, teams, and players use new warning devices mounted on helmets that sound an alarm after the head receives a serious impact. This gives an advanced warning of concussion risk (possibly before any of the medical symptoms might appear), signaling that the player should stop playing and see a medical… Read more

Measuring Your Threshold of Hearing for Sounds of Different Pitches

Science Fair Project Idea

Scientific Method

If you're like most people, you like listening to music. Have you ever wondered how your ears and your brain turn the sound waves out there in the world into the experience of music in your head? If you're interested in doing a project about how we hear, this is a good one for you. With this project, you'll do background research and make measurements to understand how the sensitivity of your own hearing varies with the pitch of the sound. Read more

Dealing with Diabetes: The Road to Developing an Artificial Pancreas

Science Fair Project Idea

Engineering Design Process

Imagine if you had to take medicine every time you ate, and you had to use a math formula to figure out how much medicine to take based on the nutritional makeup of the food, how you were feeling, and what activities you were planning to do. You might also need extra medicine throughout the day (even in the middle of the night) based on your blood glucose levels. People with diabetes who take insulin do this every day. They use finger sticks and blood glucose meters or a continuous glucose… Read more

Recycle Urine into Drinking Water for Astronauts

Science Fair Project Idea

Scientific Method

Have you ever wondered how astronauts eat and drink in space? Where does their food and water come from? Water, in particular, is quite heavy, so delivering it to space is incredibly expensive. Instead, on spaceships and space stations like the International Space Station (ISS), it is most efficient to recycle water. This includes recycling urine! In this science project, you will use methods similar to those used on the ISS to investigate how urine can be recycled into clean drinking water. Read more

Build Obstacle-Detecting Glasses for Visually Impaired People

Science Fair Project Idea

Engineering Design Process

Many visually impaired people use canes to detect obstacles at ground level. What about detecting an obstacle at face level, like a tree branch? What if you need to keep both your hands free and cannot hold a cane? Solve both problems at once with these obstacle-detecting glasses! The glasses use an ultrasonic sensor to measure distance and a buzzer to alert the user of nearby objects. You can customize the design to add or swap out features, like using a vibration motor instead of a buzzer.… Read more

Tracking SARS-CoV-2 Spread from Wastewater

Science Fair Project Idea

Scientific Method

Have you ever wanted to know where hot spots of infection are or see how viruses spread? Are you interested in seeing how this changes over time? Check out our new science project that uses data visualization tools and tested wastewater data to track the virus that causes COVID-19 over time. Read more

Blood Sugar Balancing Act: How Exercise Tips the Scales

Science Fair Project Idea

Scientific Method

You are probably very familiar with the fact that over time, exercise changes your muscles, your lungs, your bones, and even your mindset; but did you know it has an immediate effect on your body's biochemistry? You can see this in the amount of glucose (a type of sugar your body uses for fuel) circulating in your blood. Blood glucose levels change as you exercise. For most people, this is not a big deal. But for top-level athletes in the middle of intense exercise (like a marathon), or for… Read more

Sucrose & Glucose & Fructose, Oh My! Uncovering Hidden Sugar in Your Food

Science Fair Project Idea

Scientific Method

Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars—glucose and sucrose—in different foods, and investigate how sucrose is converted into glucose with the help of an… Read more

Can Peppermint Improve Reaction Times?

Science Fair Project Idea

Scientific Method

Did you know that some teachers give their students a peppermint candy on state testing days? Is it to give the kids sweet-smelling breath? Or are the teachers hoping for something more on the important testing day? In this human biology science fair project, you'll explore whether or not peppermint influences scores on different types of tests. Read more
